Indoor Unit Size(s) Mini split systems can have one or more indoor units connected to a single outdoor unit. Indoor Unit Size(s) specifies what indoor unit sizes are used in a system. For example (09 + 12) means the system includes a 9k BTU unit and a 12k BTU unit.

12 + 12 + 12 + 18

LG's devotion to providing efficient ductless solutions can be seen across the Multi F line. This ceiling cassette ductless heat pump system pairs a powerful LMU480HV outdoor condenser with four ceiling cassette indoor units. LG's Multi F ceiling cassette indoor units feature four air outlets which allow them to provide consistent air flow to the furthest reaches of large rooms. In addition to providing excellent coverage, the ceiling cassette indoor units also feature an exceptionally low profile. When installed, a grille less than 1" thick is the only visible clue that your room is receiving efficient heating and cooling from a ductless heat pump system.

Low Ambient OperationsCold temperatures can't slow the Multi F line of outdoor condensers down. This outdoor unit supports cooling operations down to 14 degrees Fahrenheit and heating operations down to -4 degrees Fahrenheit. There is also a defrost feature, which removes frost from the condenser coil in frigid conditions.

Quiet DesignThanks to a brushless direct current fan motors, both the outdoor and indoor units in this system produce less mechanical and electrical noise, allowing them to provide comfort that doesn't disrupt your home. A twin rotary compressor in the outdoor unit also limits vibration noise.

Air Flow OptionsThere are three automated air flow options with LG's ceiling cassette indoor units. In swing mode, the vertical air flow direction fluctuates to prevent temperature stratification. With the Chaos Wind feature, which cycles both air flow direction and fan speed, you can enjoy a natural circulation pattern in the comfort of your home. Finally, exclusive to ceiling cassette models is Swirl Wind, which automates both air flow direction and fan speed to produce steady comfort throughout any zone.

Jet CoolThese LG mini split indoor units feature a Jet Cool operation mode for rapid cooling. In this mode, an indoor unit observes a set point of 64 degrees Fahrenheit while the fan operates at maximum speed for 30 minutes to quickly cool your zone.

Sleep ModeWith the sleep mode and timer functions, you can set the indoor units to save energy at night. Sleep mode will incrementally adjust temperatures for an hour before the timer function automatically deactivates the units. A second timer can bet set to activate the unit in the morning to ensure that your home is the perfect temperature when you wake up.

Improved Air QualityThese mini split indoor units include anti-fungal filters to keep your air clean. These filters capture contaminants like dust and bacteria, and they are washable to ensure long term air quality.

DehumidifyLG's multi-zone indoor units include a dehumidifying operation mode. In this mode, the units' internal sensors monitor temperature and modify the set point and fan speed to remove moisture from the air.

Hot StartWhen the hot start function is enabled on a mini split indoor unit, the fan will not engage until the outdoor condenser has had the opportunity to warm the indoor coil. This prevents the unit from blowing cold air during heating operations.

Q: Can the LG system deliver heat down to 5 degrees? If so, are the BTU ratings listed the same at this temp?by Andrew S. from Massachusetts on July 24, 2016

A: LG outdoor units do not shut down based on outdoor temperature*. They will deliver heat at 5 degrees, and lower. However, their output will decrease as temperature drops toward freezing and below. For specific details on capacities at different outdoor temperatures, you can reference the Engineering Manual. If you need any help interpreting the manual, feel free to email or call us.

*The units will shut down if operating pressures in the systems are unsafe. Once pressures return to safe levels, the units will resume operation. by Chris, Product Expert
